Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, in the embodiment of the present invention, a grain particle throwing and drying device includes a drying box 1 and a placing groove 2, the inside of the placing groove 2 and the bottom of the drying box 1 are both arranged in an arc shape, the drying box 1 is placed in the placing groove 2, a feed inlet 4 is arranged on the top wall of the drying box 1, an elastic throwing net 6 is arranged on the inner plate of the drying box 1, the side of the elastic throwing net 6 is fixedly connected with the side wall of the drying box 1, a blowing fan 5 positioned on the upper side of the elastic throwing net 6 is arranged on the side wall of the inside of the drying box 1, a tensioning motor 8 and a transmission shaft 10 are arranged on the inner side wall of the lower end of the drying box 1, a transmission gear 11 and a rope winding roller 12 are arranged on the transmission shaft 10, the transmission gear 11 is engaged with an incomplete gear 9 arranged on the main shaft of the, one end of a pull rope 13 is connected with the middle part of the lower end of an elastic throwing net 6, the inner side wall of the lower end of the drying box body 1 is further provided with a heater 7, one side of the placing groove 2 is provided with a driving shaft 14, two ends of the driving shaft 14 are fixed on the side wall of the placing groove 2 through a fixing frame, one end of the driving shaft 14 is connected with a driving motor 19 arranged on the fixing frame, the driving shaft 14 is further provided with a cam 15, the cam 15 is a double-head cam, the side wall of the placing groove 2 is provided with a guide rod 18, one end of the guide rod 18 close to the cam 15 is provided with a pressing plate 17 abutted against the side of the cam 15, the pressing plate 17 is connected with the side wall of the placing groove 2 through a return spring 16, the other end of the guide rod 18 is abutted against the side wall of the drying box body 1 through a roller, the other side of, the other end face of the piston 21 is connected with the inner wall of the cylinder 20 through a return spring 22, one end of the cylinder 20 is communicated with the bottom of the drying box body 1 through an air duct 25, an air inlet 23 is further formed in the cylinder 20, a one-way valve 26 is arranged on the air duct 25, a base plate 3 is arranged at the lower end of the placing groove 2, and the cylinder 20 is fixed on the base plate 3 through a support column.
The working principle of the invention is as follows: grain particles are thrown into the drying box body 1 through the feeding hole 4 and fall onto the elastic throwing net 6, the tensioning motor 8 enables the transmission shaft 10 to intermittently rotate through intermittent meshing of the incomplete gear 9 and the transmission gear 11, the transmission shaft 10 rotates and winds the pull rope through the pull rope winding roller 12 to downwardly tension the elastic throwing net 6, when the incomplete gear 9 stops meshing with the transmission gear 11, the elastic throwing net 6 upwards throws the grain particles under the action of resilience force, the drying treatment is continued under the action of blowing air flow of the blowing fan 5 and the heater 7, the effect is good, meanwhile, the driving motor 19 drives the driving shaft 14 to rotate, the driving shaft 14 enables the guide rod 18 to push the drying box body 1 to swing left and right in the placing groove 2 through the action of the cam 15 and the reset spring 16, the throwing amplitude of the grain particles is increased, the drying effect is improved, the left and right swinging of the drying box body 1 presses air in the air cylinder 20 into the drying box body 1 through the, thereby the hot air flow at the bottom of the drying box body 1 blows to the upper end and accelerates the air circulation in the drying box body 1, and the drying efficiency of the grain particles is improved.
